Description: [T]he Tweed Champ tube amp is one of the most famous guitar amps of all time, and with good reason. Used heavily for recording, it sports just eight watts of blissful single ended tube power, with enough volume to jam with a drummer and also deliver beautiful warm tones at low volume. In just three days you can build this faithful classic. It is a beautiful reproduction of the 1950 era tweed Champ with a finger joined pine cabinet and vulcanized fiberboard motherboard, just like the original. The special kit build we are offering for this class includes a variety of optional mods and upgrades that make this one of the most versatile builds in the music world.
Description
Students will obtain a fundamental understanding of this simple circuit design, stage by stage. They will also learn the craft of point to point wiring and how to modify a circuit to shape its tone by changing component values. Through building an amplifier, students will begin to develop the diagnostic skills necessary to troubleshoot and repair other amplifiers.
Special upgrades and options include:
- All Switchcraft jacks
- 12 foot AC cord
- Hum reduction
- Boost options
- Treble bleed options
- Drilled and tapped motherboard and chassis
